MACHINE FOR HEADING UMBRELLA-RIBS.

SPECIFICATION forming part of Letters Patent No. 537,662, dated April16, 1895.

Application filed January 17, 1894- Serial No. 497,167- (No model.)

To all whom it may concern;

Be it known that I, CHARLES F. WURSTER, a citizen of the United States,residing in the city and county of Philadelphia'and State ofPennsylvania, have invented certain new and a useful Improvements inMachines for Heading Umbrella-Ribs, &c., of which the following is afull, clear, and exact description, reference being had to theaccompanying drawro ings, forming a part of this specification.

This invention comprises a machine, of novel construction, for heading,or applying heads, to the ends of umbrella ribs or the like, the machinebeing also serviceable for compressing and upsetting the ends of flutedor paragon ribs preparatory to the application of the heads thereto.

The invention comprehends two opposed dies, one of which is continuallyreciprocatzo ing relatively to the other, with means whereby the saidreciprocating die may be adjusted toward or retracted from the other dieat predetermined intervals, without affecting the reciprocative actionof the die, as will be hereinafter set forth in detail and be definitelyclaimed.

In the annexed drawings,-Figure 1 is a side elevation of a machineembodying my invention. Fig. 2 is a front elevation, the

upper or reciprocating die being depressed. Fig. 3 is a partial verticalsection, as on the line 0c0c of Fig. 2. Fig. 4 is a plan of one of thedies detached. Fig. 5 represents the end of a fluted rib as it appearsbefore and after 5 being compressed and headed. V

' The numeral 1 designates the supporting frame, which is a substantialcasting of proper form to receive and sustain the various cooperatingparts of the machine. Fitted to suitable guide-ways in thefront of thisframe is a vertically reciprocative plunger, 2, to the upper end ofwhich is connected one member of a toggle 3, the other member of thelatter being in turn operatively connected with a 5 suitably-disposedeccentric or crank, 4, on an upper shaft 5. This shaft is mounted inboxes 6 on the frame, and is provided with an appropriate flywheel 7 anda driving pulley or pulleys 8 to which motion may be transmitted from asuitable source of power.

Hence during the rotation of the shaft the plunger 2 will be rapidly andcontinuously reciprocated. Pivotally connected, as at z, with the uppermember of the toggle, is the forward end of a rearwardly-extending rod,9, the other or rear end of which is similarly connected with a pivotedtreadle lever 10. Normally the toggle occupies the broken orrearwardly-inclined position indicated in Fig. 1, thereby maintainingthe plunger ele- 6o Vated, yet, obviously, when the rod is forcedforward, the toggle is straightened, and the plunger, perforce,depressed. It will be seen that the movements of the rod to operate thetoggle may be effected by properly moving the treadle. The lower arm ofthe latter is preferably connected, by a powerful retracting spring, 11,with the bench upon which the machine is supported, the tendency ofwhich spring is to draw said arm forward to main- 7o tain the plunger,through the intermediate connections, in the normally elevatedposition'. It will be obvious that when the toggle is opened, it doesnot impair the rapid reciprocative action of the plunger by theeccentric above.

. Fitted to the lower end of the plunger, is a die 12, the acting faceof which is suitably shaped or recessed to meet the requirements of theparticular work in view. Immediately below this die is disposed aco-acting die 13, which occupies a fixed relation to the path of theupper die, whereby when the latter is depressed, it will come in contactwith the lower die, or nearly so. In the present instance die 13 issecured to a threaded support 14 that extends freely through oppositeorifices in the base of the machine and the bench, said support beingprovided with nuts 15 that take against the upper side of said 0 baseand the under side of the bench, respect ively, and thereby firmlysecure in place the support and its die. Byproperly manipulating thenuts the latter parts may be nicely adjusted vertically in respect tothe upper 5 die. The working faces of the dies are each provided withrecesses 15, 16, the corresponding recesses of the two dies being inalignment so that they will register when the upper die is depressed.The recesses 15 are :00

V-shaped in cross-section with an expanded inner portion 15 while theadjacent recesses are similarly formed and provided with sockets 16.

To compress and up-set the end of a fluted rib, preparatory to theapplication of a head thereto, that is, after the usual eye, a, has beenaffixed, said end, with its eye turned upward, is inserted in therecess-of the lower die, and the treadle lever is actuated to depressthe upper die, the corresponding recess therein embracing the end of therib, andleythe rapid strokes of the upper die effecting the end in view.(A and B Fig. 5, indicate the rib before and after the operation justdescribed.) This done, the treadle is released to permitthe upper die tobe returned by the action of the spring to the normally-elevatedposition.

To apply a head to the tip of the rib, a metallic cap, I), is placedthereon, and the latter inserted in the recess 16, with the cap in thesocketed portion. The upper die is then depressed as before, and, as aresult of around the tip of the rib and firmly secured thereto.

Where the head is applied to solid ribs or rods, the recess 15 is notused.

I claim as my invention- In a machine for heading umbrella-ribs, &c.,the combination, with a supporting frame and a die thereon, of avertically-reciprocative plunger guided in the frame directly above saiddie, a co-acting die on said plunger, a shaft provided with a crank oreccen trie, a toggle the upper arm of which is hung directly on saidcrank or eccentric and the lower arm of which is connected with theplunger, a pivoted treadle lever, and a link connecting the upper arm ofsaid lever with the toggle, substantially as described.

In'testimony whereof I have hereunto atfixed my signature in thepresence of two subscribing witnesses.
